The collapse was caused by human error, said Scott Powell, a Manitoba Hydro spokesperson.

Powell said there was a missing cotter pin on one of the assemblies, which are held up by guy-wires a.k.a tensioned cables. He said that missing pin, along with improper guy-wire tension, allowed a nut to work itself loose during some extremely high winds, which caused the collapse.

He added that the tower had been up for less than 10 days and that the tower's contractor will replace it and pay for the materials needed for a new build.

CBC reported last year that five towers had collapsed in 2017 due to human error. That prompted the union that represents some of Hydro's electrical workers to ask for a full investigation into the matter.

The International Brotherhood of Electrical Workers (IBEW) Local 2034 said it wasn't aware of the latest collapse and has asked Hydro for details.
